Abstract

In our semisolid casting method, magnesium alloy slurry was made using an inclined cooling plate instead of electromagnetic or mechanical stirring during solidification. The semisolid slurry was fed into a twin-roll caster and continuously cast into 2 to 3 mm thick sheets with a maximum width of 200 mm. The microstructures of the sheets contained refined and globular primary crystals. The most important factors are casting temperature and twin-roll speed that influences sheet casting. The sheet obtained by this process was examined for roll workability, hardness, and Erichsen value. The results were excellent; thus, the casting sheet is suitable for deep drawing.
